Fox News contributor Juan Williams on Sunday slammed the "Fox News Sunday" panel and Republicans in general for scrutinizing Sgt. Bowe Bergdahl, the soldier recently released as a prisoner from the Taliban.

"This young man suffered. He was caged. His parents suffered. And yet people want to argue about the father’s beard. They want to say they shouldn’t have a parade. Let the military decide," Williams said on "Fox News Sunday." "Not us sitting here on this panel and not all the political people on the Republican side who have flip-flopped — flip-flopped in the most craven way."

Many lawmakers initially supported negotiating for the release of Bergdahl and celebrated his ultimate freedom, but then backtracked to criticize the deal and Bergdahl himself.

While most criticism directed at the administration over the prisoner exchange came from Republicans, some Democratic lawmakers expressed discomfort with the deal. Sen. Dianne Feinstein (D-CA) slammed the administration for not following the law by failing to consult Congress before freeing five Guantanamo detainees in exchange for Bergdahl.
